Concrete pulverizer is a heavy-duty machine designed to break down large chunks of concrete into smaller, more manageable pieces. It is commonly used in the demolition and recycling industries to crush and pulverize concrete structures or concrete rubble from demolished buildings or bridges.
The primary purpose of a concrete pulverizer is to reduce the size of concrete debris, making it easier to handle, transport, and recycle. The pulverizer typically consists of a sturdy frame, crushing jaws or plates, and hydraulic or mechanical mechanisms to apply force and pressure onto the concrete.
"To use a concrete pulverizer safely and efficiently, follow these general steps:
Before using the concrete pulverizer, inspect it thoroughly to ensure that all parts are in good working condition. Pay attention to the condition of the crushing jaws or plates, hydraulic or mechanical components, and any safety features.
Equipment Preparation:
Attach the concrete pulverizer to the designated heavy machinery, such as an excavator, using a compatible quick coupler. Make sure the attachment is securely connected and properly locked in place.
Wear appropriate personal protective equipment (PPE), including a hard hat, safety glasses, gloves, and steel-toe boots. Ensure that the work area is clear of personnel and hazards that could interfere with the operation.
Position the heavy machinery and concrete pulverizer for optimal access and maneuverability. Ensure that there is ample space for the pulverizer to operate without any obstructions.
If the concrete pulverizer is hydraulically operated, make sure the hydraulic system is properly activated and pressurized. Familiarize yourself with the controls and levers that operate the pulverizer attachment.
Approach the Concrete Structure: Direct the excavator towards the concrete structure or debris you intend to pulverize. Slowly approach the target, allowing the crushing jaws or plates of the pulverizer to make contact with the concrete surface.
Activate the hydraulic controls or mechanical mechanism to apply pressure onto the concrete. Gradually increase the force to break down the concrete into smaller pieces. Pay attention to the crushing progress, avoiding unnecessary excessive force that may damage the equipment or result in unsafe conditions.
Move the heavy machinery, or manipulate the excavator’s arm or boom, as necessary to access different areas of the concrete structure. Take care to distribute the crushing force evenly and cover the entire target area.
As the concrete is pulverized, use the pulverizer’s jaws or plates to separate any rebar or metal reinforcements from the pulverized concrete. This sorting process facilitates recycling and reduces waste.
Repeat the crushing and sorting process as needed until the desired result is achieved. Adjust the pulverizer’s position and pressure application based on the specific characteristics of the concrete structure.
After completing the pulverization process, inspect the pulverizer and heavy machinery for any damage or excessive wear. Properly clean the equipment and remove any residual debris.
Always follow the manufacturer’s guidelines and instructions for the specific operation, maintenance, and safety procedures related to your concrete pulverizer. If you are new to using a concrete pulverizer, consider receiving proper training or guidance from an experienced operator or equipment provider to ensure safe and effective use.
Hydraulic pulverizers utilize hydraulic power to operate their crushing mechanism. Here is a general overview of how hydraulic pulverizers work:
The hydraulic pulverizer is connected to a hydraulic system, typically powered by an excavator or other heavy machinery. The hydraulic system provides the necessary force and pressure to operate the pulverizer.
The hydraulic pulverizer is equipped with strong, serrated crushing jaws or plates that are hydraulically controlled. These jaws or plates apply pressure onto the concrete, breaking it down into smaller pieces.
The hydraulic cylinder, powered by the hydraulic system, is responsible for applying the pressure onto the crushing jaws or plates. When activated, it extends and retracts, creating the crushing force needed to pulverize the concrete.
The hydraulic system includes valves and controls that regulate the flow and pressure of hydraulic fluid to the hydraulic cylinder. The controls are typically operated by the excavator operator, allowing precise control over the crushing process.
To use the hydraulic pulverizer, the operator positions the pulverizer jaws or plates over the concrete structure or debris to be crushed. Once in position, the operator activates the hydraulic controls to apply pressure, causing the crushing jaws or plates to close on the concrete.
As the hydraulic cylinder extends, the crushing jaws or plates exert a powerful force on the concrete. The serrated edges of the jaws or plates grip and break down the concrete into smaller pieces.
Some hydraulic pulverizers allow for adjustable jaw or plate openings, allowing operators to control the size of the crushed material. This feature enables the pulverizer to produce different-sized materials based on the specific requirements of the project or recycling process.
During the crushing process, the hydraulic pulverizer can also help separate any rebar or metal reinforcements embedded within the concrete. The pulverizer jaws or plates can hold and manipulate the rebar, allowing it to be sorted and separated from the pulverized concrete.
The operator closely monitors the pulverizing process, adjusting the hydraulic controls as needed to achieve the desired result. The crushing operation continues until the concrete is effectively pulverized into the desired size and any rebar or metal has been separated.
The precise operation and features of hydraulic pulverizers may vary depending on the specific manufacturer and model. It is crucial to consult the manufacturer’s guidelines and instructions to understand the proper operation, maintenance, and safety procedures for a particular hydraulic pulverizer."
"Choosing an excavator concrete pulverizer involves considering several factors to ensure the optimal match for your specific needs. Here are some key considerations to help guide your selection process:
The first and foremost factor to consider is whether the concrete pulverizer is compatible with your excavator. Check the manufacturer’s specifications to ensure that the pulverizer is designed to be used with your excavator’s size, weight, and hydraulic capabilities.
Evaluate the size and weight of the concrete pulverizer. It should be appropriate for the demolition and recycling tasks you intend to perform. Consider the space limitations at your worksite and any transport requirements when selecting the size and weight of the pulverizer.
Assess the crushing force of the pulverizer. The crushing force should be sufficient to effectively break down the concrete structures or debris you will be working with. Take into account the compressive strength and thickness of the concrete to ensure the pulverizer can handle the required workload.
Decide on the type of crushing mechanism you need. Concrete pulverizers typically come with either crushing jaws or plates. Jaws are suitable for crushing concrete structures, while plates work well for pulverizing concrete slabs and walls. Consider your specific demolition requirements and choose the appropriate configuration.
Determine if you need the ability to adjust the jaw or plate openings. Adjustable openings allow you to control the size of the crushed material, which can be useful for recycling purposes or meeting specific project requirements.
Ensure that the concrete pulverizer is constructed with high-quality materials and durable components. It should be able to withstand the rigors of heavy-duty demolition work. Look for features such as reinforced steel construction, wear-resistant components, and robust hydraulic systems.
Check for essential safety features, such as proper guarding, hydraulic overload protection, and safety locks. These features help minimize the risk of accidents and protect the operator and surrounding personnel.
Consider the reputation and track record of the manufacturer. Look for reputable companies known for producing reliable and high-performance concrete pulverizers. Additionally, assess the availability of spare parts, maintenance support, and after-sales service to ensure long-term support for your investment.
Evaluate the cost of the concrete pulverizer in relation to your budget. While it’s important to find an excavator concrete pulverizer that meets your requirements, it’s also essential to consider the overall value and return on investment it offers.
Lastly, seek user reviews and recommendations from other professionals in the industry who have firsthand experience with different concrete pulverizer models. Their insights can provide valuable information and help you make an informed decision.
By considering these factors, you can select an excavator concrete pulverizer that aligns with your specific requirements, offers optimal performance, and provides long-term durability and value."
Driven by a hydraulic cylinder, hydraulic pulverize achieves the purpose of crushing objects by controlling the angle between the movable jaw and the fixed jaw. Jiangtu hydraulic pulverizer uses the speed-increasing valve to hydraulically return the oil in the rod cavity of the oil cylinder to the rodless cavity and then increase the speed when the hydraulic cylinder extends outwards, reducing time spent on empty stroke. While keeping the thrust of the oil cylinder unchanged, the operating speed of the oil cylinder is increased and then the working efficiency of hydraulic pulverizer is improved.
The oil cylinder is designed to be installed upside down, which avoids bumps and scratches on the piston rod.
If you need to deal with large quantities of heavy demolition materials or steel bars, hydraulic concrete pulverizer can provide extra breaking force to remove the steel bars.
A key factor is your excavator weight and hydraulic requirements. You need to choose a pulverizer that fits your excavator or buy an excavator that fits the pulverizer. Pulverizer and excavator size depends on the type of work you do and the material you need to handle. The larger the material you need to grab and crush, the larger the size of your hydraulic pulverizer and excavator.
To choose the model of hydraulic pulverizer and excavator, you can also consult Jiangtu engineer from China leading hydraulic pulverizer factory.
Cylinder-powered concrete pulverizers have stronger breaking force for better handling of thicker concrete.
